About this file
This file is a technical procedure document for the initial startup and break-in process of Caterpillar SSDG/EDG diesel engines (D-398, D-348, or 3406 series). The procedures outline a comprehensive checklist for safely commissioning newly overhauled or installed engines, beginning with fluid filling, heater energization, fuel system priming, and pre-lubrication of turbochargers. Critical steps include manually barring the engine over by hand to ensure proper rotation without binding, starting the engine locally while monitoring oil pressure as the primary concern, and conducting a 30-minute no-load operation period with continuous observation for leaks, abnormal noise, and vibration. The document specifies a minimum 24-hour under-load operation requirement before vessel departure, mandatory oil sample testing for fuel dilution analysis, and completion of a baseline DEMPS assessment after approximately 100 engine hours. Additional requirements include testing all safety devices, zeroing engine hour counters post-overhaul, recording maintenance completion in machinery history logs, and performing the first oil and filter change in accordance with the maintenance planning card with corresponding oil sample submission for laboratory analysis. This procedure document directly supports the related Coast Guard RFQ 52000QR260028236 for CGC RESOLUTE SSDG Long Block, as it establishes the operational commissioning standards that contractors and Coast Guard personnel must follow upon engine delivery and installation.

SSDG/EDG INITIAL START AND BREAK-IN PROCESS
The subject of initial startup and break-in procedures for D-398, D-348, or 3406 series engines isn’t provided in the CATERPILLAR Service Manuals.
Please utilize the following guidelines to complete this process.
1. Fill all fluids to normal operating levels.
2. Energize all heaters and allow sufficient time (24 hrs) for them to bring temps to within their designed range.
3. Prime the fuel system. Check for any fuel leaks.
4. Pre-lube engine and pour a quart of oil into the turbocharger housing (s) via the oil inlet/supply line to provide lubrication prior to initial start.
5. Bar the engine over by hand (DO NOT USE STARTER) at least two full revolutions or more in the same direction as normal engine rotation (do not rotate backwards) to ensure it doesn't bind up at any point. IF the engine feels abnormally tight or reaches a point you can’t turn it over by hand STOP and investigate possible causes. DO NOT ATTEMPT TO START until the issue is identified and corrected.
6. Start the engine locally and observe the gauge panel for oil pressure (Note: oil pressure is the most critical concern at this point). Once oil pressure has been confirmed check all other parameters for normal operation.
7. Listen for any unusual noise and check over the engine multiple times for leaks while continuing to monitor the gauge panel.
8. If the engine is free of leaks, has no abnormal noise, and all parameters (oil, fuel, jacket water, raw water) are within the normal range continue to operate for 30 minutes to allow temperatures to stabilize. Continue to check for any signs of leakage, abnormal sounds, or vibration.
9. After 30 mins of no load operation and the engine is operating properly (temps & pressures are within the normal operating ranges) place the engine under load and continue to look & listen for anything abnormal.
10. Recommend a minimum of 24.0 engine hours (under load) before getting underway. Remember to pull and test oil samples for fuel dilution. This will give you the ability to monitor engine performance over an extended period to identify and correct any potential issues before getting underway
11. Test all safety devices for proper operation.
12. Remember to “zero” out your engine hours following overhaul and note the date in your machinery history.
13. Remember to record this MPC as complete.
14. Once the engine has approximately 100 hrs. you will need to complete a base line set of DEMPS.
15. Complete your first oil and filter change IAW the MPC and send off oil samples for testing.
